Dokotala akakuuzani kuti muyesedwe ndi ultrasound, ndi chinthu chodziwika bwino kwa ife tsopano. Koma nthawi zina akanena kuti "Ndikufunika kuchita ultrasound scan ndi contrast," mumaopa pang'ono komanso mumachita chidwi, sichoncho? Kodi "contrast" ndi chiyani? Kodi zingawononge chilichonse? Chifukwa chiyani ultrasound yanthawi zonse sikokwanira? Lero, tikambirana za mayankho a mafunso onsewa m'maganizo mwanu m'njira yosavuta kwambiri m'nkhaniyi.
Mwachidule, kodi Contrast-Enhanced Ultrasound (CEUS) ndi chiyani?
Kuti timvetse izi, choyamba tiyeni tikumbukire tanthauzo la ultrasound scan. Ultrasound scan imaphatikizapo kutumiza mafunde amphamvu omwe sitingamve m'thupi, ndipo mafundewo amatuluka m'ziwalo zomwe zili mkati ndikupanga chithunzi pa kompyuta.
Kusanthula Kosiyanasiyana (CEUS) ndi njira yapamwamba pang'ono ya njirayi. Apa, madzi apadera amalowetsedwa mumtsempha wanu kudzera mu kannula kakang'ono (mzere wa IV). Ichi ndi chomwe timachitcha "kusiyanitsa." Madzi awa ali ndi thovu la mpweya mamiliyoni ambiri, laling'ono kuposa maselo anu amagazi. Izi zimatchedwa "mabulovu ang'onoang'ono" kuti zitheke.
Pamene thovu izi zikuyenda m'mitsempha yanu yamagazi kupita ku ziwalo zosiyanasiyana, pamene mafunde a phokoso ochokera ku makina a ultrasound agunda thovu zimenezi, zimagwedezeka kwambiri, ndikubwezera mafunde a phokoso mwamphamvu kwambiri. Zotsatira zake, madera okhala ndi kusiyana kumeneku amawoneka owala kwambiri komanso omveka bwino pachithunzi chomwe mukuwona pa kompyuta.
Mwachidule, kusiyana kumeneku kumagwira ntchito ngati kuyatsa 'tochi' yaying'ono pa ziwalo zomwe zili mkati mwa thupi. Izi zimathandiza dokotala kuona bwino momwe magazi amayendera m'ziwalozo.
Kodi cholinga chachikulu cha mayeso a CEUS ndi chiyani?
Madokotala amagwiritsa ntchito mayesowa nthawi zambiri kuti adziwe matenda enaake m'chiwindi ndi impso, komanso amagwiritsidwa ntchito pofufuza ziwalo zina zingapo.
| Chiwalo chowunikira | Zochitika zodziwika |
|---|---|
| Chiwindi | Kuzindikira zilonda za khansa ndi zosakhala khansa. |
| Impso | Kuzindikira khansa ya impso, ma cysts, ndi matenda. |
| Ziwalo zina | Kuyang'ana momwe magazi amagwirira ntchito komanso momwe ziwalo monga mitsempha yamagazi, mtima, ndulu, kapamba, ndulu, ndi chikhodzodzo zimagwirira ntchito. |
| Chithandizo cha khansa | Kuyang'anira momwe chotupa cha khansa chimayankhira chithandizo. |
Kodi ubwino wa CEUS ndi wotani poyerekeza ndi mitundu ina ya ma scan?
Nthawi zina madokotala amagwiritsa ntchito CEUS pamodzi ndi kapena m'malo mwa mayeso monga CT scans ndi MRI scans chifukwa ili ndi ubwino wake wapadera.
- Ndi yotetezeka ku impso: Kusiyanitsa komwe kumagwiritsidwa ntchito mu CT scan nthawi zina kumatha kukhudza impso. Chifukwa chake, CEUS ndi njira yotetezeka kwambiri kwa munthu amene ali ndi matenda a impso kapena allergy ku CT contrast.
- Zabwino kwa ana aang'ono: Kujambula kwa CT kumagwiritsa ntchito X-ray. Ultrasound sigwiritsa ntchito X-ray. Chifukwa chake, CEUS ndi yotetezeka kwa ana aang'ono, kupewa kukhudzana ndi kuwala kosafunikira.
Kodi mayesowa akuyenda bwanji? Mukumva bwanji?
Njira yonseyi ndi yosavuta kwambiri. Imachitika m'magawo awiri.
Gawo 1: Kujambula Ultrasound Mwachizolowezi
Choyamba, katswiri adzapaka jeli wonyezimira pakhungu lanu ndikuyikapo chipangizo chonyamula m'manja chotchedwa transducer. Panthawiyi, adzaona malo enieni omwe chiwalocho chili ndikujambula zithunzi zosavuta. Simudzamva kupweteka kulikonse panthawiyi, kupatula kumva kunjenjemera pang'ono.
Gawo 2: Kujambula kwa Ultrasound ndi contrast
Kenako, dokotala kapena namwino adzaika kansalu kakang'ono (IV) mumtsempha womwe uli m'dzanja lanu kapena m'dzanja lanu ndikubaya madzi osiyanitsa m'thupi lanu. Mungamve kupweteka pang'ono singano ikalowetsedwa ndipo dzanja lanu lingamve kuzizira pamene madziwo akulowa.
Akangolowa m'thupi, katswiriyo adzayang'ananso ndi kujambula zithunzi. Apa ndiye pamene angathe kuona bwino momwe magazi akulowera m'ziwalo.
Musadandaule! Ma thovu a mpweya awa (`ma microbubbles`) mosiyana samakhala m'thupi kwa nthawi yayitali. Amaphulika pakapita kanthawi, kenako mpweya wopanda vuto umasungunuka m'magazi ndikutuluka m'thupi mukapuma.
Mayeso akatha, gel idzachotsedwa ndipo kannula yomwe ili m'dzanja lanu idzachotsedwa. Pambuyo pake, mutha kupita kunyumba popanda vuto lililonse.
Kodi ndiyenera kukonzekera bwanji mayeso asanayambe?
Kawirikawiri, izi sizimafuna kukonzekera kwambiri. Chomwe muyenera kuchita ndikuvala zovala zomasuka komanso zomasuka. Komabe, kutengera chiwalo chomwe chikufufuzidwa, nthawi zina mungalandire malangizo apadera.
- Kusala Kudya: Ngati ndi mayeso a m'mimba, mudzalangizidwa kuti mupewe kudya kapena kumwa kwa maola angapo mayeso asanachitike.
- Chikhodzodzo chonse: Ngati mukuyesedwa chikhodzodzo, mungapemphedwe kuti mumwe madzi ndikubwera kudzayesedwa chikhodzodzo chanu chikadzaza kwathunthu.
Chofunika kwambiri ndikutsatira malangizo omwe dokotala wanu kapena chipatala chanu amapereka.
Kodi pali zoopsa kapena zotsatirapo zake pa izi?
Choyamba, ukadaulo wa ultrasound ndi njira yotetezeka kwambiri yopanda zotsatirapo zoyipa.
Komabe, anthu ena angakumane ndi zotsatirapo zoyipa kuchokera ku contrast fluid. Komabe, izi sizimachitika kawirikawiri . Zotsatirapo zoyipa izi nthawi zambiri zimakhala zazing'ono. Tiyeni tiwone zomwe zili.
| Mulingo wa zotsatira zoyipa | Zizindikiro zomwe zingatheke |
|---|---|
| Zotsatira zoyipa zochepa (nthawi zambiri kudzichiritsa) | Mutu, nseru, kuyabwa kapena ziphuphu pakhungu, kupweteka kapena kutentha pamalo obayira jakisoni, kumva kutentha m'thupi, kusasangalala pachifuwa, chizungulire, kukoma kwachilendo mkamwa. |
| Zotsatira zoyipa zochepa (Chithandizo chamankhwala chingafunike) | Kusanza kwambiri kapena kutsekula m'mimba, kuchepa kwa njira zopumira (bronchospasm), kutupa kwa nkhope, kukomoka, kuthamanga kwa magazi kutsika. |
| Zotsatirapo zoyipa kwambiri (Zosowa kwambiri) | Anaphylaxis - Ichi ndi chiwopsezo chachikulu cha ziwengo chomwe chingayambitse imfa. Komabe, izi sizichitika kawirikawiri. Ogwira ntchito zachipatala nthawi zonse amakhala okonzeka kuthana ndi mavuto otere. |
Malinga ndi ziwerengero, zotsatirapo zazing'ono zimachitika mwa anthu ochepa ngati 5 pa 100 (5%). Zotsatirapo zoopsa zimachitika mwa anthu osakwana 1 pa 10,000 (osakwana 0.01%). Choncho musachite mantha kwambiri ndi izi.
Kodi ndilandira liti lipotilo?
Zithunzi zomwe zapezeka kuchokera mu mayesowo zimaphunziridwa mosamala ndi katswiri wa radiology ndipo lipoti limakonzedwa. Kenako, lipotilo limaperekedwa kwa dokotala wanu. Pomaliza, dokotala wanu adzakufotokozerani zotsatira za lipotilo.
Uthenga Wopita Nawo Kunyumba
- Kusanthula kwa Ultrasound Kosiyanasiyana (CEUS) ndi njira yapamwamba yowunikira yomwe imagwiritsa ntchito madzi apadera okhala ndi thovu laling'ono la mpweya kuti ione bwino momwe magazi amayendera m'ziwalo za thupi.
- Izi ndizothandiza kwambiri pozindikira matenda a chiwindi ndi impso. Ndi njira ina yotetezeka kwambiri m'malo mwa CT scan kwa odwala impso ndi ana aang'ono.
- Kuyesa kumeneku ndi kosavuta. Palibe kupweteka kulikonse kupatula kannula kakang'ono kolowetsedwa m'dzanja ndikupereka madzi osiyanitsa.
- Zotsatirapo zoyipa za mankhwala otsutsana ndi khungu sizimachitika kawirikawiri. Musachite mantha. Ngati muli ndi vuto lililonse la ziwengo, dziwitsani dokotala wanu musanayesedwe.
- Ndikofunikira kwambiri kutsatira malangizo operekedwa ndi chipatala kapena dokotala wanu (monga kusala kudya) kuti mupeze zotsatira zolondola.
